Pope Francis is greeted by children in traditional Mongolian costumes outside the Apostolic Prefecture in Ulaanbaatar's Kahn Uul district, Friday, Sept. 1, 2023. Pope Francis is traveling to Mongolia to encourage one of the world's smallest and newest Catholic communities. It's the first time a pope has visited the Asian country and comes at a time when the Vatican's relations with Mongolia's two powerful neighbors, Russia and China, are once again strained.
